====== Simple Improvements for Simple Scripts ======

Did you ever suddenly notice that something simple you've been doing for years could be vastly improved with just a little bit of tweaking? I did yesterday concerning the transfer of files with netcat (e.g. when nobody got sendfile installed and standard paranoia forbids simply using scp instead) and figured I should share my sudden "enlightenment" ;-)

<code bash|ncsend>
#!/bin/sh

host=$1
shift

tar cv "$@" | pv -brt | nc -q0 $host 23000
</code>

<code bash|ncrecv>
#!/bin/sh

netcat -l -p 23000 | pv -brt | tar xv
</code>

Note: piping to ''[[http://www.ivarch.com/programs/pv.shtml|pv]]'' is optional \\

**Edit**: fixed a word splitting bug and specified a default port
